[GRASS-user] editing rasters

Well, the problem was "solved" with r.null, apparently (i used the -r flag
for removing the NULL value bitmap). The resultant file is a georreferenced
tif and i succesfully edited it in gimp and re-imported it to grass

Even so, the error i mentioned in my previous message persists...

thank you again for this great help,

JM
